Original No. 1,495,120, dated'May' 20, 1924. t Serial 110.665,984, ledOctober 1, 1923. Application for I reissue filed December 24, 1924.vSerial No. 757,938. l `l To all whom t may concer/n:

- Be it known that/I, RUSSELL siding at Brooklyn, in the county of Kingsand State of New York, and a citizen of the United States, have.invented` certain new and useful'lmprovements in Burners, of which thefollowing is a specification.

`This linvention relates to burners and more particularly to burners foruse in connection with gas heaters of the instantaneous type. t Theprincipal object of the invention is to provide a burner which will befree from corrosion and which corrosion is now caused the water ofcondensation. Another 'object 'off-the invention is the provision of aburner including a copper tube wherein a screen usually employed inburners of this type, is insulated and supported in spaced relation tothe side walls of the tube for keeping the screen cool at all timeswhereby to eliminate back iire.

A 'Still further object of the invention is to provide a burner with aburner head removable from theburnerand so constructed as to prevent thewater| of condensation from flowing into the flame openings.

A still further object of the invention is to provide a burnerwhereinthe number of parts is reduced toa minimum thereby rendering thesame simple in construction, cheap of vmanufacture and highly efficientfor the purpose intended'.

`With these and other objects in view, the invention resides in certainnovel construction and combination and arrangement of parts, theessential features of which are hereinafter fully described, areparticularly pointed out in the *appended drawing, in which: Y

Figure 1 is a vertical longitudinal sectional view through my improvedburner construction. 'h

Figure 2 is a horizontal sectional view on the line 2-2 of Figure 1.

Figure 3 is a similar view on the line 3-3 of'Figure 1. l

Figure 4 is adetail View ofthe burner head per se. p h g Y y Referringmore -particularly to the drawing, thereference numeral 10 designates acopper tube which is formed from flat strip STYLES, re-

h of material and the ends of lwhich are provided with co-actingportions 11, 11 which form a seam after the striphas beenl formed intothe tube 10.

I find that by usingcopper as a `burner tube, the corrosion usuallycaused by the water of condensation is prevented thereby adding. greatlyto the life of thetube. This tube 10 is open yat'both ends and adjacentthe lower end there is formed within the tube `l() a cement core 12,provided'with a conical shaped bore'13 terminating in arestricted=portion` 14. 5 This core 12 is formed by inserting a mold'inthe'lower end of the tube and'pouring the cement about the core andpermitting it to dry'. While the cement is in its softened condition, asuitable perforated cylinder or cylindrical screen 15 has its lower endanchored in the core 12 as at `16, whereby thev same is supported invertical Aaxial alignment with the conical shapedv bore 13. Bysupporting the screen 15in vthis manner it willrbe seen that the same isspaced y.from the sidewalls ofthe tube 10 and also insulated'therefromwhich and'prevent back fire. y I

vBy. reason of' he use ofv the core 12, the tube 10 may be ofuniformdiameter throu hout its length, thereby enabling stock tubing to beemployed and eliminating the necessity1 for 'shaping the tubing tolprovide the passages which are no w formed in the core. Thus, by theuse of'iny core characterized by yserves to keep the screeny cooled atall times a tapered, mixing passage for yincreasing the I possibility ofderangement to a minimum and enable the burner to operate at itsmaximum1 efficiency for a comparatively long time. v l A burner head 17is provided for partially closing they upper end ofv the tube and thesame is formed with a plurality vof depend# ing'lugs 18 which areadapted to frictionally engage the inner wall of the tube lO'forremovably securing the burnerhead thereto. The burner head 17 is furtherprovided with an annular flange 19, the exterior wall of which may bebeveled as at 2O for co-action varranged and co-related as to reducethe.

with the inner` wall vofthe screen 15 whereby to also serve to retainthe burner head in per cylinder will not corrode la foraminated cylinderinsulated place and to hold the screen in vertical alignment with theaxis of the'tube. The burner head 17 is provided with a plurality ofupturned lips 21 which co-act with one of the open ends of the tube 10so as to provide flame openings 22 whereby to permit the fuel to flowand be ignited. The ends of the lips 21 terminate in a downwardly turnedportion 23 which portion overhangs the walls of the tube so as to carryoff the water of condensation thereby preventing the same from flowinginto the flame opening 22.

The fuel supply pipe 24 enters the lower end of the tube 10 and is heldin axial alignment therewith by means of a bracket 25, said pipe 24extending part way into the mixing chamber which mixing chamber isdefined by the bore 13.

In operation of the burner, the gas 1s introduced into the mixingchamber by means of the pipe 24 and air sucked in through the lower endof the tube by reason of the restricted portion of the bore, whichportion sets up a vacuum for sucking the air. The principle ispractically the same as that used in the Bunsen burner and the air andgas after being mixed in the chamber 13 passes up and out through thescreen 15, the screen serving to break up the particles of mixture,after which the same is ignited at the fiame openings 22. It will beseen that with a burner of this construction, same will be free fromcorrosion as the copby reason of the water of condensation and suchwater will be carried ofi in the manner previously described.

While I have described what I deem to be the most desirable embodimentof my invention, it is obviousthat man of the details may bevariedwithout 1n any way departing from the spirit of my invention and Itherefore do not limit myself to the exact details of constructionherein set forth nor to anything less than the whole of my inventionlimited only by the appended claims.
